Hi Thierry,
OK, it will work with ISA, however the clients must have the firewall client
installed, because it does sound like secondary connections are required. So,
if the CiscoTV is software that runs on Windows OS's then it'll work. If there
are dedicated devices of some sort, then it won't work because you can't
install the firewall client on them. However, if they support SOCKS 4.3a and
you can configure the proper protocol definitions, the SOCKS proxy (filter) can
manage the complex connecitons. You just have to make sure that authentiation
is not required for the Protocol Rule you create to support the dedicated
devices.
HTH,
Tom

Hi Tom,
Thank you very much for your answer.
I have experimented Cisco IP TV through a socks proxy: it didn't work.
Inside Cisco IPTV dialogs, through the rtsp protocol, Cisco IP TV client and
server negotiate UDP connection ports. The server sends packets to the client
according to the negotiation. It seems that a socks proxy can't relay UDP
packets to a client that don't have a UDP destination port equal to a UDP
client call source port that has been previously relayed.
I'm glad to see that with Winsock proxy (Firewall service) it works.

Hi Levesque,
Why don't they work with SOCKS? What is the technical problem with it?
With the Firewall client installed, you can access any protocol, regardless of
how complex, through the ISA firewall.

Hi,
I knew that CISCO IP TV calls don't work with socks proxy.
Is there the same problem with the Firewall service (Winsock
Proxy protocol) of ISA?
More generally where can I find a list of applications that
don't work with the Firewall service of ISA.
Thank you very much
